1.) a musical genre, the in-between of punk and metal. Hardcore is NOT the music of the pig squealing myspace whores with scene haircuts, though many believe it to be so. Hardcore music typically consists of simple power chords repeated in variations, simple yet loud drums, and a vocalist yelling, not screaming, about either how straight-edge he is, or how straight-edge he isnt. hardcore is NOT abreviated "hxc" and is not spelt hardxcore. Hardcore fans typically wear camo shorts or tight black pants, black shirts of their favorite bands or funny things (like the "spread the joy" shirt from locoroco, not a "how to win at videogames" shirt you bought at hot topic while you were buying your sister new make-up to replace all the eyeliner you stole from her), and occasionally a bandanna around their head, not their neck, and PUMA, NIKE, ADDIDAS, or VANS shoes. Hardcore fans do not wear suits or ties, do not cross-dress, and do not think its cool to kiss guys, even if they're anti-homophobic.

2.) an adjective to describe something done that most people do not have the balls to do.

1.) "Mickeys crew is a hardcore band"

2.) peeing on your friend's sister because she stole your money, windmill kicking your refridgerator open so hard that the container of milk flies out of the door-shelf and into your hand, then ripping the lid off with your teeth and downing all 2 gallons in a single sitting just so that your little brother won't have any milk for his cereal when he wakes up.

A style of rock that originated as a variation of punk rock in the late 70s/early 80s. This variation was a harder, heavier version of punk. It is a largely underground genre of rock. Most of the greatest hardcore bands were in the mid-80s.

Rise Against is an example of modern hardcore, whereas Atreyu is mistakenly labelled hardcore.

Hardcore is a term used to justify some dislike. This term is often used by those who are not "hardcore" but want others to believe they are. Bands are often critized for being "not hardcore" because they are vastly more successful than the people bitching about them.

Steve: That band sucks ass they arn't even hardcore.
Brian: Your just pissed cuz they don't live in their parents basement anymore...like some people i know. (looks at Steve and winks)
